You do not need to regulate the fuel, the carbs do that, the pump just supplies fuel to them.There is no fuel regulator.

1987 fzx 700 will turn over but not start. carbs are clean and adjusted. runs great when you bump start it. Fuel pump comes on even after engine is warmed up. Not sure what else to check.


chec electrical 1st its the weakest link--batt may not be at 12.6v-needed for a coil ign--corrosion/connections cud be bad like a ground-plugs-cables-ignition module may be worn---u need a fuel pressure test to confirm a bad pump--getta repair manual or library has troublshootn guides

How to find the construction year of my yamaha fzx 750 ?


The bike was only made for two years 1986-87. Most if not all parts are interchangeable. There was also a 700 made for the US over the same years and those parts are mostly compatible as well.
